To provide light source equipment of high quality by canceling unevenness of brightness.

It has a light guide body 4, which has a light incident end surface 41 and a light emitting surface, and an LED 2 arranged adjoining to the light incident end surface 41. The light guide body 4 has a light emitting mechanism, which has surfaces formed in satin-like finish in either side or both side of the light emitting surface and its back surface 44 by the side of its opposite, and local lens-line formation parts 44a1 and 44a2. The local lens lines, which constitute the local lens-line formation parts 44a1 and 44a2, are formed in different directions with the direction of the peak light of the maximum strength light Lo of the brightness distribution at the incident position of the incident light emitted from the LED 2 and incident to the light incidence end surface 41. Further, they are prolonged radially, in which the brightness become 90% or less of the peak brightness, passing through the incident position of the maximum strength light Lo. The local lens-line formation parts 44a1 and 44a2 have the total area of 30% or less of the area of the light emitting surface.
